Boku no Risou no Isekai Seikatsu episode 3

Just one day after officially welcoming Chise as his second wife, the household is still settling into its new rhythm when a familiar face appears at the door: their neighbor, Lavmier. Norn, ever the gracious host in this strange world, calls for Chise to greet their guest. With a simple introduction, he presents Chise as his second wife, making the new family structure publicly known.

This revelation hits Lavmier with an unexpected force. It turns out that Lavmier has had her eye on Norn for some time. Seeing the quiet and demure Chise now occupying such a privileged position in his life stirs a powerful pang of envy within her. As she watches the new wife, a silent question lingers in the air: why her and not me?

Oblivious to the subtle romantic tension brewing next door, Norn soon finds himself lost in thought. He attempts to unravel complex theories regarding magic, the rules of this world he finds himself in, but the concepts remain frustratingly out of reach. Deciding to clear his head, he opts for his current simple pleasure: a stroll through the local park. A voice calling out to him. Startled, Norn turns to find none other than Lavmier standing right there. She takes matters into her own hands.
